There are plenty of spectrum analyzer phone apps you can download for free. When you are setting up your system you push it to just start ringing and the app will show you what freq’s Are ringing, go to the EQ section and pull out those freq’s until the feedback goes away. You can also buy a noise plug, an xlr plug that emits pink noise (all freq’s at the same volume) plug it in and use your analyzer to flatten out the system, this will make a huge difference in your overall sound as well. When your done save the the EQ or the whole setup as a show.

Love the DL32R but struggle with stage monitor feedback. Have used the graphic EQ with limited success but it not easy and not quick. Automatic feedback elimination would be very cool, or the capability to use a third party plugin like Waves.

Like everyone else, I'd like FB suppression. We are a self engineering 5 piece band and have recently switched to a dl1608 from an old mackie cfx12 with 2 dbx FB suppressors. So far, we love the 1608 in almost every way, but are struggling a bit with feedback, especially for the on stage monitors. If the 1608 eq/peq/rta functions also included feedback detection and/or suppression, that would be great.

The Line 6 StageScape mixer has built in feedback suppression (switchable on/off), which I found very effective - I miss the facility now I'm using a DL32R. For me, this would be a very welcome addition to the DL32R.

I'd prefer a feedback DETECTOR, not eliminator - detectors make preset decisions. I'd just like to be able to see which freq is clipping and adjust. But even better, make ANY EQ on ANY In or OUT SWITCHABLE between GRAPHIC or PARA. I like Parametrics on my AUX and MAIN outs, it gives finer control.
